Bicameral system, a system of government in which the legislature comprises two houses. The modern bicameral system dates back to the beginnings of constitutional government in 17th-century England and to the later 18th century on the continent of Europe and in the United States.
One form of resistance was slowing down the picking of cotton. Slaves would intentionally go slower so that they could have an easier time in the fields. This was combatted by the Southern Plantation owners after a while by whipping the slaves severely during their first picks and then mandating that they had to pick at least as much cotton every time after.
Another form of resistance was to run away. The Underground Railroad helped thousands of slaves escape to the north and to freedom.
